Lolo Jones said that remaining a virgin has been harder than training for the Olympics in an interview with HBO's "Real Sports."

Jones, 29, who hopes to finally pick up an Olympic medal for the United States at the London Games in the 100 meter hurdles, first made the announcement about her virginity on Twitter in March, when asked by someone if she was still, in fact, a virgin: "Yes I'm a virgin. #1 reason why I'm single bc guys deuce out when I won't put out. I do so to honor God & future husband."

Jones also spoke with Mary Carillo about her rigorous, six-hour-a-day training routine as she prepares for the London games, her close family circle and her difficult upbringing that has influenced her choices as an adult. She even explained the origin of her unusual name, Lolo.

"I've always been called 'Baby Lo' around the house because me and my mom have the same name -- both Lori -- and people would call and say 'Can I speak to Lori?' so I've always been Baby Lo. Somehow it just morphed into Lolo.

"But yeah, not a lot street cred when you're running track. 'And in lane 5, Baby Lo!' So yeah, we toughened it up a bit."
